img27Consumption of solvents during the degreasing process

Consumption of solvents during the degreasing process. The consumption of solvents during the degreasing process is quite significant and, according to German data, amounts to approx 2,8 kg / m2 h. Means, that e.g.. at the liquid surface in the basin 0,63 m2 degreased over time 9 hours 3600 kg of products consuming 16 kg of trichlorethylene. Despite the relatively high consumption of the solvent, the cost of degreasing, according to some specialists, is lower than in the case of degreasing in aqueous solutions., due to the high energy consumption for heating the baths while degreasing with alkaline water solutions, which more than compensates for the cost of an expensive solvent. Limit concentration of oils and greases, dissolved in "tri” during degreasing should not exceed 10%, because then the amount of vapors in the upper part of the apparatus is too small and the degreasing is insufficient. During degreasing, the oil content is checked at least once a day.
